METHOD OF AND APPARATUS FOR PROPELLING PRODUCER-GASES.

SPECIFICATION forming part of Letters Patent No. 503,842, dated August 22, 1893.

Application filed May 15, 1893- Serlal No. 474,217. (No model.)

To all whom it may concern:

Be it known that I, WILSON H. FORBES, a citizen of the United States, residing at J eannette, in the county of Westmoreland and State of Pennsylvania, have invented new and useful Improvements in Methods of and Apparatus for Propelling Producer-Gases, of which the following is a specification.

This invention relates to the working of producer or generator furnaces having steam blast appliances for forcing the gases to regenerator furnaces employed in the manufacture of glass, and for other purposes.

In this type of apparatus it is essential to introduce the steam at high pressure into the producers or generators, for the purpose of obtaining the requisite draft to force the gases through the gas main to the regenerators, and the steam at the necessary high pressure cuts out the brick work structure, which is damaging and therefore objectionable.

The objects of my'invention are to enable the producers or generators to be worked with steam at less pressure; to increase the heating capacity of the producer or generator gases, and propel them to the regenerators or other places to be utilized without cutting out or damaging the producer or generator brick work, or danger of an explosion.

To accomplish all these objects my invention consists in the method and apparatus hereinafter described and claimed for propelling and increasing the heating capacity of the producer or generator gases.

In the accompanying drawing the figure is a sectional side elevation, illustrating gas producers or generators, a gas main leading therefrom, and a boiler furnace connected with the gas main in accordance with my invention. I

In order to enable those skilled in the art to make and use my invention, I will now de I do not deem it necessary to illustrate the regenerator furnaces, as they are, of well known construction and arrangement.

The numeral 3 indicates a boiler furnace, having a steam conveying pipe 4 leading from the steam dome 5, and having branches 6 connected with tuyeres 7 which deliver steam to the producers or generators for draft purposes. A pump 8, mounted upon, or otherwise arranged in juxtaposition to the boiler furnace, is provided with a steam pipe connection 9 with the steam dome 5, and this pump is geared to the shaft of an exhausting and forcing apparatus, such as a rotary blower 10, having the exhaust pipe 12 connected with the smoke box 13 of the boiler furnace, and the branch 14 connected with the gas main 2. The pipe 12 and the smoke stack or chimney 15 of the boiler furnace may be provided with dampers or valves 16 and 17, whereby the products of combustion from the boiler furnace may be caused to pass out of the smoke stack or chimney, or into the exhausting and forcing apparatus. The pipe 14 leading from the exhausting and forcing apparatus is preferably provided with a valve 18 which permits the products of combustion to flow into the gas main, but prevents back flow into the pipe 14:. When the producers or generators are working, the products of combustion from the boiler furnace are conducted into the gas main, and serve to propel the producer or generator gases through the gas main to the regenerator furnaces, or other place or places where the gases are to be utilized, and, by the mingling of the products of combustion with the producer or generator gases, increasing the heating capacity of the latter, which is a very desirable feature in working glass furnaces where a very high temperature is essential.

By propelling the producer or generator gases through the medium of products of combustion from a separate furnace forced into the gas main, it is possible to materially reduce the pressure of the steam delivered to the tuyeres of the producers or generators, which is a very important and desirable feature, in that ordinarily the gases from the producers or generators are forced through the gas main by the pressure of steam in- 1 By my invention this is avoided, and the heating capacity of the producer or generator gases is materially increased without danger of an explosion'which would likely result if I atmospheric air were forced into the gas main, and without liability of choking up the gas main by the rapid accumulationof carbon, as

would likely occur if steam were introduced directly into the gas main to the gases in transit to the regenerator furnaces.

By forcing the products of combustion from the boiler furnace into the gas main, the gases from the producers or generators are propol-led to the regenerator or other used inthe manufacture-of glass, and tarot-h r pn rposesinrfactories, a d the heating'capaei y of thcgprod-ucer or generator gases is materiailly inc eased; hile the steam p essure employed t erea-te the usual artificial draft in the predncerser ge erators can be g eatly e,-
